YEs, back in the mid 80's I believe in 1984, 85 & 86. CP had a 10k on the last Sunday of Bonus Weekends (CP only had TWO Bonus Weekends at this time). It was intended as a way to build traffic/crowd for the end of the season. The efforts that went into running the event far outweighed any return so the race was ended.
The course was interesting as it went approx. like this: started on boardwalk by the Hotel Breakers went out along the beach through the parking lot all the way to the Chausee Road toll Booth, the runners then came back up the parking lot onto the midway and ran the "loop" through the park out into Camper Village and then ended back at the start point.
